Question 1166332: The planet-year of a given planet is the time it takes the planet to make a complete revolution
around the sun. An Earth-year is simply equal to 1 year. Simplifying the laws of celestial mechanics,
the square of the duration of a planet-year is proportional to the cube of the distance between the
planet and the sun. Knowing that Jupiter is roughly 5 times as far from the Sun than the Earth, then
the duration of the Jupiter-year is approximately
(A) 5 years (B) 7 years (C) 9 years (D) 11 years (E) 13 years
